Weather in July
Temperature
In Selwyn, West Virginia, temperatures reach their average annual highs in July, measuring 86°F (30°C) and a minimum average of 63.1°F (17.3°C).Heat index
July's mean heat index is estimated at a torrid 96.8°F (36°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
